A previously undisclosed federal plan to stem gun trafficking to Mexico is reportedly languishing in Washington out of fear of public opposition from the National Rifle Association. According to the Washington Post, agents at the Bureau of Alcohol, Tobacco, Firearms and Explosives have proposed a system that would force gun dealers to report sales of multiple rifles and shotguns. But the plan has stalled at the U.S. Department of Justice for months amidst fears the NRA will mobilize members and lobbyists to thwart it in Washington. An estimated 80 percent of weapons used by Mexican drug traffickers come from the United States.
